BY VMMW' A TTORNEYJ United States Patent 3,167,828 SECURITY GUARD FQR WINDOWS Clarence L. Hutchisson, in, 1657 Springhiil Ave, Mobile 17, Ala. Filed Jan. 24, 1963, Ser. No. 253,588 4 Qlairns. (Cl. Ell-71) The present invention relates to new and useful improvements in window guards and more particularly and specifically to a novel and improved metallic grill for fixed installation in a window opening to prevent ingress and egress therethrough.

The prior art discloses various forms of fixed and removable security guards or grills for installation in window openings. Some of these prior art structures require alteration of the window framing or the building surrounding the window opening, and some do not. Most of the prior art structures are extremely complex, costly, and impractical, while others are ineffective for the purpose for which they are intended.

s It is, therefore, a general object of the'present invention to provide an extremely simple, inexpensive and effective security grill for quick installation in a window opening which will eliminate the numerous disadvantages inherent in prior art structures designed for like purposes.

Another object of the present invention resides in the provision of a metallic security guard or grill which may be quickly and easily installed in an existing window opening without removal or modification of any part of the window or window framing components.

A further object of the present invention lies in the provision of a metallic security guard or grill which may be quickly and easily removed from a window opening in which it has been previously installed without defacing the window or window framing components.

A still further object of the present invention rests in the provision of a metallic security guard or grill for a window opening which is quickly assembled from a partial knock-down condition and installed in place in a window opening to aitord complete security against ingress and egress, and which aflords .a degree of security comparable to an integrally and permanently installed window guard.

Still another object of this invention is the provision of a metallic security guard or grill which is readily adaptable for manufacture in several forms rendering it adaptable for use in windows having wood, metal or masonry jambs or frames.

Still another object of this invention is the provision of a security guard for window openings which is relatively attractive and which affords a minimum of visual or aesthetic obstruction when installed.

Still further objects and advantages of the present invention will become more readily apparent to one skilled in the am when thefollowing general statement and description are read in the light of the accompanying drawings. 1

The nature of the present invention may be stated in general terms as relating to a metallic security guard or grill for quick installation in an existing window opening consisting of vertically spaced upper and lower cross aliases Patented Feb. 2, 1965 like numerals designate similar parts throughout the several views:

A security grill for a wooden framed, double-hung window is illustrated in FIGS. 1-5 of the accompanying drawings. In this embodiment of the present invention, a metallic security grill, generally designated 10, is provided for installation in the lower half of a typical double-hung, woodenframed window 12, below the upper outside sash element thereof, not shown. In FIG. 1 of the drawings, the typical window 12 is shown to include vertical side frame elements 14 each of which is provided in lateral opposition with

recessed guide channels

16 and 18 in side by side relationship adapted to slidably receive the lower sash 20 and the upper sash, not shown. The

frame elements are secured in typical fashion flush against the

jamb portions

22 and 24 of the building structure defining the window opening. A typical sill member 26 completes the disclosed portion of the framing elements of the window.

The guard grill, generally designated 10, constituting the preferred embodiment of the present invention, can be best seen in FIG. 1 of the drawings as including a bottom cross rail 28, and an upper cross rail 30 in parallel with the bottom rail and spaced vertically thereabove.

upper cross rail element 3% is of shorter length than the lower cross rail element and is provided adjacent the rerail components, vertically disposed bar elements rigid-. 7

1y supported by said cross rail components at horizontal- 1y spacedv intervals, rigid window frame engaging flanges on the remoteends'of, the lower cross rail component,

a third cross rail component engaged on the upper cross 1y interlocking the third mil with the upper cross rail component.

Referring now to' the accompanying drawings in which I mote ends thereof with slotted openings 38 vertically therethrough. The third component of the grill consists of a third rail element as, shown in FIG. 1 in an elevated position above the previously described grill components.

The third cross rail element 40 consists of a channel member having vertically depending perpendicular flange elements 42 at the remote ends thereof, similar to flanges 34 on the lower cross rail, and which are provided with screw fastening openings 44 therethrough. The upper cross rail is additionally provided adjacent each end thereof with a depending'eye loop 46 vertically aligned above and in registry with the slotted openings 38 in the upper cross rail element 3%. The third cross rail element is further-provided with a series of openings 48 vertically therethrough and spaced longitudinally thereof to register with the vertical bar elements 32 previously described.

' In installation of the security grill, the unitarystructure V the lower regionof the window, andthe flanges are slidably moved to position the grill with the upper and lower rails in horizontal position laterally of the Window. Thereafter, the third rail element is inclined to permit vthe installation of the flange elements on the opposed ends thereof within the opposed channel recesses below the top sash element, the upper rail is moved inwardly of thejwindow'to assume a position invertical alignment above the lower rail and in transverse alignment between the recessed channels in which the flange elements of thelower rail are then positioned, and the thirdrail ele- .ment'is then lowered telescoping the spaced openings therein about the upper projected ends of the verticalbar elements to bring the third rail'element into juxta-: position with the upper cross rail element and to locate the eye elements on the remote ends thereof in dependency through the slotted openings inthe remote ends of the upper cross element. .The assembled grill may then be temporarily positioned vertically of the windowopening between; the sill and the bottom of the upper sash ele-' ment by the use of a wedge block below the grill seated on the window sill, whereupon screw fasteners may be inserted through the openings provided in the fiange eleprojects vertically through the vertical slotted cpenmg 72 ments on the lower cross rail and. the-third rail intothe P wooden :frame. elements. Thereafter the wedge block maybe removed and padlocks may then'be secured with.

their shackles interlocked through the depending eye formations-on the third rail element below the upper cross railqthussecurely interlocking the uppercross rail' and the third rail element and securelylocking the guard grill in the window opening. i i

In FIG. 4 of the drawings there is shown a modification or the structure disclosed in FIGS. 1 through 3 where-f in the dependingeye loop 46 of the third rail element is'eliminated and replaced by a vertical slotted opening 50 through the third rail element. which is locatedso as i to register vertically above the vertical slotted opening 38 in the upper cross rail element adjacent the end there.

of. As is seen in'FIG. 4, the shackle of apadlock, shown in dotted line, willthen be'inserted through the two Vera tically aligned slotted openings in the adjacent rail elements to securely lock the elements one to the other for the. reasons hereinbefore described.

securely fix the cross rail to the vertical window framing element. g

In FIGS. 6, 7 and 8 there is shown a modified form of the security .guard construction hereinbefore described which is particularly adaptedfor installationin Windows having masonry jambsi' in this modified form the masonry jarnb, generally designated at 61%, is equipped with vertically spaced horizontally projectingj'rnetallic lugs 70' the base ends of which are firmly embedded within the jamb. Each lug is, providedadjacent'its projected. end with a vertical slotted opening 72. I

Y Thesecurity guard assembly associated with the projecting lugshereinbefore describedconsists 0i anupper cross rail 74 substantially identical tothat-described in connection with the preferred embodiment of this invention which includes azdepending eye loop 76 adjacent each- The lower cross rail element 78 of the modified form is substantiallyidenticalto the upper ,cross rail form except that the depending eye loop of the upper form is replaced by a vertically depending metallic tab Shwhrch in thelower projecting lug to'locate andretain the lower rail, ,and-the lower lug in'interlocked relationship.

The installation of the modifiedfsecurity guard in a masonry-framed windowiis substantially identical in se-.

quential steps as; the installation.hereinbefore described" relative to the preferred embodiment.

In PEG. 8 of'the drawings there is shown an alternate formof an intermediate cross rail for the'modified form oi the guard which is in substance identical withthe intermediate rail of the'preferred embodiment except that I a third metallic lug 8Zisembedded in the masonry jamb to project therefrom and to provide a vertical slotted opening for reception of-the nut and bolt fasteners 84 which interlock the intermediate rail and'theintermediate lug. 1

. tween" the frame engaging .abutinents'and' frame guides In FIG. 5 of the drawings there isshown an alternate construction which may be used in connection with the burglar guard described in respect to FIGS. 1 through 3. This alternate constructionconsists or" the use ofariinter mediate cross rail which: would be necessitated only I I where the vertical height of the window and burglar guard were suchasto require an intermediate strengthening member... In this. alternate construction an intermediate or'centralcross'rail element 52, taking the. form of a ilat' i I metallic bar, is positionedtransversely oft-the vertical bar elements which telescope through spaced openings-in the rail'element and which are'welded, as at 54, thereto to rigidly interconnect the vertical bars and :theYrail ele ni'ent; The'extreme ends of this intermediate rail elementproject laterally beyond each of theremote verticalbars of the guard for a distance: substantially equalto the projection of 'the upper cross; rail element. The projecting portion of the intermediate rail'is provided with a bracket-and'the slotted opening in the intermediate cross slotted'opening 5s adjacent'its end." .Cooperatively with the intermediate cross rail an L-shaped bracket .58 has the footgportion 60 thereof se'cured, as at 62, to the verticalwiridow frame with the leg element fi l-thereof horizontallyv overlying. the-adjacent end of the intermediate rail and: two screw; fasteners, 66, shown as. nut and bolt combinations, ,are' secured verticallyfthrough the L-shaped in the preferred embodiment ofmy invention. Such deviations in lateral dimensions between diifer'ent windows.

The particular and specific forms. and'applications of the invention .hereinbefore described are: intended to illustrate the concepts of the'jinvention, but they are .not'in tended to limit the inventionub'eyond. the requirements of 1 For examplatheg dimensioning and spacing of theconiponent elements may be varied, as maybe their'maiterial,:withoutadeparting" from the spirit of theiinvention, 'The guard may be; lutilize'dfull length of a window,1doo'r or otherf'wall open ing without departing from the intended scope of the distheprior art and the appended claims.
